Be it known that I, CHARLES H..ToM-Lm-. son, citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Draw -Bar Carriers, of which the following is a specification. My invention relates to a movable hanger or draw-bar carrier and comprises certain new and'novel means of movably suspending the frames carrying the draw-barsto provide for radial or lateral movement.

The invention herewith described is a division of an application filed .by applicant Jan. 26, 1907,.Serial No. 354,352,.

- The present invention consists in pivotall securing a bar to the bottom of a car withmeansofmovably suspendingthe free end thereof (for radial movement) -jupon a channel angle or similar bar and means of attaching the movable frame thereto. I attain these and other objects by the mechanism illustrated in the accompanying drawings in which'- Figure 1 is a side elevation of mydevice showing the supporting yoke and spring in normal position. Fig. 2 is a front elevation of the carrier with one side in-vertic'a'l-section taken through the line 00 of Fig. 1. Fig. "3isa horizontalsection of the-carrier taken through the line X X of Fig. 1. Fig. 4 is a plan view of the draw-bar carrier. and the supporting means showing the a ipliczition'o the pivotal bar and means 0 supporting it for radial or lateral movement. Fig. 5 shows a section of a track with one end inclined downward illustratinga grade with sections of two cars coupled upon the grade with the draw-bars and couplers supported by the movable frame and pivotal bar and its supporting mechanism.

In the construction of my device, I refer to use a frame comprising a base 1 wit two downwardly depending arms 2 and 3 spaced ipartleaving an opening 4. Vertical flanges Hand 6 are made integral with said arms and ipaced apart and connect with the horizontal IP86! and lower flanges 7 and 8 respectively, m in conjunction therewith form recesses )r casings to inclose and support the comression springs 9, the purpose of which will 1e described hereinafter.

Hangers 10 are provided for each casing vith the upper extremities 11 turned at an 2 angle with the. body portion and adapted to a-l-ine with suitable apertures formedv in the horizontal flanges 7. The lower extremities 12 of the hangers have eyes formed thereon with. apertures formed therein at-right angles to the apertures formed inthe upper extremitiesgfi opening 13. is. provided in thelowen'eigtremities and side walls of the arms 2 and 3- topermit the lower eXtremi-' ties of; the hangers to jbeinserted therein leaving'the enlargetl -lowerport-ion 14' of the hangers extendinginwardly flush with the Mi e. arms 2 and 3 retaining them, in place and preventing the draw-bars from-catching under the inner walls of the arms iipentheir return to normal position vlfelieved of undue strain or pressure cansedby the cars being on a different grade or'pl'an when coupled. A'sleeve 15 is interposed between' the inner faces of the enlarged lower portions of the hangers and mounted uponthe pin 16 which is held in place by the cotter pins 17 and 18.

The hangers l0 and sleeve 1-5 when connected together form a substantially inverted-sha 'ed.yoke which is ada ted to move vertically as will be described hereinafter.

v The coil springs 9 are inserted in the cas-v ings/i formed by the flanges as hereinbefore described with the lower extremities resting on the horizontal flanges 8, and the upper extremities contacting with the under portion of the angular endsj ll of the hangers 10 therebyyieldingly suspending the parts comprising the inverted yoke. Throughgoing bolts 19 pass. downwardly through the flanges 8 leaving the lower extremities.

projecting below the arms 2 and 3 and they are retained in place by any ordinary fastening means.

The coil compression springs 9 or other supporting means are made of such a size or tension as will counter balance the weight of the inverted yoke, the draw bar and coupling mechanism that they yieldingly support whereby the draw-bar and coupling mechanism are movably retained on a plane for coupling purposes under normal conditions as, for instance, when the cars are upon the same grade.

The above describes the functions and structure forming part of the application described in Serial No. 354,352 and forms no part of the present invention.

The invention comprising the subject matter of present application, will now be described.

A standard 20 is secured to the bottom of The dependingportion of the bracket is hi furcated to receive the end 26 of the drawbar 27 and is journaled upon a bearing, a pin 28 is provided for vertical movement of the draw-bar and coupling device. The base.

1 of the frame is secured to the bar 23 adj acent to the end 24. The free end. 24 of the pivotal bar 23 extends rearwardly from the trucks and is movably supported by the inwardly extending plate 29 which is attached to the beam 30.

It will be apparent that the coupling mechanism and appliances are supported by the means described and vertical and lateral movement of the couplers is provided for.

By the arrangement above described, a convenient supporting mechanism is provided with means to attach my draw-barcarrier to any car, no matter how much the platform of the car over-hangs the trucks. To make the a plication it is only necessary to change the ength of the pivotal bar 23. A channel .U or similar shaped bar can be used in place of the plate 29 and beam 30 to support the free end of the pivotal bar 23 if desired.

The operation of my device is as follows: The rear extremities of the draw-bars 27 are pivotally attached for vertical movement to the bracket 25. The free end of the pivotal bar 23 is movably supported upon -the plate 29 for lateral movement and carries the frame of the draw-bar. and appliances thus providing for combined vertical and lateral movement. The free end of each draw-bar 27 is supported by the sleeve 16 between faces of the enlarged portions 14 of the hangers 10, and the tension of the springs 9 are adjusted to maintain the draw-bar and coupling devices at the same plane as the car body under normal conditions. .WVhen one .(or both) of the cars are upon a differ-' ent grade as shown in Fig. 5, a strain or pressure is brought to bear upon the sleeve 16 forcing the sleeve and hangers supporting it downward by the tilting of the car body and compressing the springs 9 to such an extent as .will keep the draw-bars and coupling devices on a plane with each other when coupled, although one or both of the cars are running upon difierent grades with respect to each other. \Vhen the sleeve and hangers forming the inverted yoke are relieved from the strain or pressure, the sleeve automatically returns to its normal position for coupling purposes.

Having fully described my invention, what I claim and desire to secure by Letters Patent is:

1. In a draw-bar carrier, the combination of a flat bar secured to the lower portion of the car; of a yoke-shaped frame supported by said bar for lateral movement, a yokeshaped yielding supporting means mounted on said frame for vertical movement, a bracket secured to said fiat bar having means to pivotally connect a draw-bar, and means to support the free end of the flat bar.

2. In a draw-bar carrier, the combination of aibar secured to the lower portion of the car; of ayoke-shaped frame supported by CHARLES H. TOMLINSON.
